E3 - Firewall Software & Devices - TCP Port numbers

Firewall Software And Devices

Firewall software is increasingly popular to help protect from malicious computer attacks. If you are running any type of firewall software you must ensure that it allows E3 to communicate on TCP port 3050 and also TCP port 3051.

If E3 is unable to communicate with its database or with the Activation Service, try disabling your firewall to identify the source of the problem.
